To n35 whom it may concern.'

33e it lm'own that I, HAROLD' H. TIMIAN, e, citizen of the United States, residin et Kokomo4 in the oonntyof Howard and tete of indiane, lieve invented' e new and use; :Eni Variable Hot-Spot Foei Passage, of .which the following is e, speciiication,

The obje/ of my invention is to produce 'e.etfnetni e which may be associated .with

'ine fuel reapply passage ofen 'internal eom- Emotion engmeto automatico!! canse the inei mixture to ne veriably e eeted by e heating eienient in inversey relation to the fue?. demend, diet is 'to soy, when theen with throttle adjacent its ioe fuel mixture will besibeeterreletive heetin' than idoine l.. .l xe wenn ied poeition jezwi to e when the engine is rainning with the edieeent ite open position.

The eoeomgenymg drawings illustrate my invention ifig. 'l is a vertical axial seciion oi my improved device with adjacent ombions of the nel pessage indicated in fnii linee end the structure arranged forusefin v clamped upon ienges 1l bybolts 14 so esto 'form connections with pipes formingpert of the exhaust system oi the engine. The interior of main body 1G, is longitudinaliy ribbed, es indicated et l5, and et one Aend is adapted to receive e valve ring 16 heving en ineiined valve Seat 17 surrounding :i main pessege i8 normally closed by a, grav ity valve 19 nivoted at 20 upon ring 16. At

- one side, edjeeent the free e'nd of`valvel9,

iiie ring 16 is perforated to form a. yhiv-pass;

2l arranged to direct materiel passing therethrough to and upon the adjacent portion of the wall of the body l0. A.

The reeeiving end of body 10 is adapted i be attached to e supply pipe 22 in which (eleehusuai throttle vaive 23 is mounted, and the delivery side of bodyl() is adapted to be ettaehed iothe fuel passage 24.

The ring 16 being separate from body 10,

absorbing ribs 12. The oir? it is apparent that, by reon ein pin i5. this' ring 16 ma be set into any fdeeire'd. angular relations ip to oody 10, ,The rote.u

table connection 'between body l() and the @o pipe connections 13,13 also permits 'intensive local heating oi enydesi-red segment of Weil 19. Consequently, by e proper en ginder adjustment of ring. 16 and eouplin ee `13, 13, the' opening 21 may be so positione ,as to direct materiel flowing therefrom to.

any' desired portion of the well of body 1G so es io. time obteineny deeired lieeting fe'e'et.

Whether the ringl be arranged for hori- 'to zontelor vertical iiow of the fuel mixture,

the .velve 19 is normally cloeedby gravity. When; the throttle. 23 is Wide open, the How o fuel through the structure 'will be at suffieient velocity, and the mess of the mineure ie with suqient inertie to raise veve 19 from its seat so that the mein body of the mix- 'tnre dow will bethrongh opening 18 and time avoid, ivo e considerable extent, the' heated wall of mein body 1G, the velocity e0 of themixture' stream being such es to suecesefully-cerry the liquid or veporized Content of the mixture to thee-vlinders. When the throttle is at or neer its closed position, however, the Velocity of the mixture which @E posses the- 1throttle, end the mese of ,this

mixture, is too mail to littlie/iaive 19 from ite seat and consequently the mixture ,will be diverted through ssege 2i? and thus caused 'to strike the body 10 and thus become heated so that. the decreased velocity will not resuii in precipitation of the fuel content. l; will, of course, be understood that, et inter-mede ate positions of the throttle, the valve 19 @5 will ooeupy intennediete positions so that more or ess of the'ael mixture will pass throughopening 19 or ivy-pees 21, the veve 19A riding Aulpon tine fuel, mixture stream at e greater or lesser distance from its E00 l seat 17. f
